Mechanical ventilation: What to look out for when planning ventilation

Mechanical ventilation is an essential part of an efficient ventilation concept in both residential and commercial buildings. But what do you need to consider when planning ventilation in order to get the best out of a mechanical ventilation system? Proper planning and implementation of mechanical ventilation not only means more comfort for occupants, but also installs improved energy efficiency and a healthier indoor climate. In this blog post, we'll take an in-depth look at the basics, benefits and tips for effective mechanical ventilation. Let's delve into the world of mechanical ventilation and find out which aspects are crucial when planning ventilation systems.


What is mechanical ventilation and how does it work?

Mechanical ventilation is an active ventilation system in buildings that uses fans or ventilation units to control and improve air exchange. It ensures a continuous supply of fresh air and the removal of stale air in order to optimise the air quality in closed rooms.

Mechanical ventilation works efficiently and in a controlled manner to ensure constant air quality. Monitored and regulated by sensors, it adapts the air supply to the respective room conditions and filters out pollutants and pollen as required.

There are different types of mechanical ventilation systems, including centralised and decentralised systems. While centralised systems ventilate the entire building with a central ventilation unit, decentralised systems can control and ventilate individual rooms separately.

Mechanical ventilation makes a significant contribution to the well-being and health of residents by ensuring optimum air quality and efficiently regulating energy consumption.

In addition, modern mechanical ventilation systems offer a high degree of flexibility and adaptability to the individual needs of a building. The ability to regulate the ventilation intensity as required and control it room by room enables the system to be utilised optimally and efficiently.

Overall, the benefits of efficient Mechanical ventilation are manifold and contribute significantly to a healthy, comfortable and energy-efficient indoor climate.


Basics of ventilation planning for mechanical ventilation systems

When planning mechanical ventilation systems, it is crucial to consider the individual requirements and conditions of the building. Mechanical ventilation systems ensure a controlled supply and exhaust of air to create a healthy indoor climate. The first step in ventilation planning is to analyse the building in detail, including room usage, window arrangement and possible sources of noise.

It is important to calculate the required air volume flow for each individual zone or room to ensure sufficient ventilation. Factors such as room size, room height, the number of people in the room and the utilisation of the room play a decisive role. The selection of the ventilation units and the positioning of the air outlets must fulfil the specific requirements of the building. We are happy to support you right from the initial phase of the planning process to ensure that the ideal customised ventilation solution can be implemented together with you. Provide us with your planning documents and we will support you from the start of your project through to handover and deliver the required solutions in the form of your customised Ventomaxx ventilator.

The integration of filters into the forced ventilation system is essential to ensure good air quality. Filters can remove pollutants, particles and allergens from the air, which is particularly important in heavily frequented rooms or in areas with high levels of air pollution.

Structural conditions and regulations must also be taken into account. The ventilation system must be installed in accordance with the applicable standards to ensure the safety and efficiency of the system. Here, it is advantageous to work with experienced specialists and planners to find an optimal solution.

The importance of maintenance and care for Mechanical ventilation systems

Regular maintenance and care of mechanical ventilation systems is crucial to ensure that they continue to function efficiently and reliably. Proper maintenance enables potential faults to be recognised and rectified at an early stage, which in turn extends the service life of the system.

An important aspect of maintenance is cleaning the ventilation system. Dust, dirt and impurities can affect the performance of the fans and filters, which can lead to reduced air quality and increased energy consumption. Regular cleaning of the ventilation components optimises air circulation and increases the efficiency of the system.

The operation of the Mechanical ventilation control unit should also be checked regularly. An incorrectly set or defective control unit can install unwanted energy consumption or inefficient operation. The performance of the system can be improved by having the control unit professionally checked and, if necessary, recalibrated.

Another important point is to inspect the ventilation units and ducts for possible damage or leaks. Leaks in the ducts can install unwanted air exchange with the environment, which affects the energy efficiency of the system. Regular inspections allow potential problems to be recognised and rectified at an early stage.

In addition to regular maintenance by specialised personnel, it is important that the building's users are informed about the correct handling and use of Mechanical ventilation.
